DIE FOR CUTTING LEATHER.

SPECIFICATION forming part of Letters Patent N. 346,929, dated August10, 1886.

Application filed March 20, 1886. Serial No. 195,932. (No model.)

To all whom it may concern.: v

Be it known that I, HENRY LoEsER, of Boston, county of Suffolk, State ofMassachusetts, have invented certain new and useful Im- 5 provements inDies`for Cutting Leather and other Materials, of which the following isa specification, taken in connection with the drawings accompanying andforming a part hereof, in which- Figure 1 is a plan view showing theshape of the die-knife. Fig. 2 is a section of the device shown in Fig.l. Fig. 3 is a plan view of a modied form of die. Fig. 4 shows a pieceof leather with the strip cut therefrom. 15 My invention relates to adie, constructed as hereinafter described and claimed, for cuttingshoe-strings or analogous narrow strips from a piece of leatherorsimilar -material, instead of cutting such strips by spinning the 2opiece of material against a knife, as is a common practice. l

In the drawings,A denotes a block, one face of which is cut out to forma single recess, D. B is a helical knife having uniform spaces c 25between its convolutions, said knife being secured in the recessed faceof the block A by a metallic packing material, b, as lead, which may herun, while in a molten state, into the spaces a, the knife beingmeanwhile properly spread in any suitable manner, as by inserting smallblocks of Wood of a uniform thickness between the convolutions oftheknife.

With the completed die, formed in the manner described, it is obviousthat shoe-strings or other narrow strips may be rapidly cut, either byplacing the die on the material and striking the die, or by putting thedie on a press and forcing the material against it.

The die may be of a circular form, as represented in Fig. l, or it maybe oval, as in Fig. 3.

I claim as my invention- A cutting-die consisting of a block having inits face a single recess and a helical knife secured in said recess by ametallic rpacking material, as lead, filling the spaces between theconvolutions of said knife in the said recess of the block,substantially as set forth.
